    LILLY EXTENDS HART-SCOTT-RODINO WAITING PERIOD FOR MCKESSON TENDER OFFER
 
  Eli Lilly and Company announced today that it has agreed to extend the
waiting period under the Hart-Scott-Rodino Antitrust Improvements Act in
connection with its tender offer for McKesson Corporation until Thursday,
November 3, 1994. The waiting period, as previously extended, was scheduled to
expire on October 27, 1994. Lilly said its discussions with the Federal Trade
Commission (FTC) were progressing, and that Lilly was hopeful that it will
complete the FTC clearance process by November 3.
 
  However, no assurance can be given that this will occur. For this reason, as
well as to permit McKesson time to complete the previously announced
distribution of stock of a newly formed McKesson corporation to its
stockholders, it may be necessary to further extend Lilly's offer to purchase
the common stock of McKesson, which is currently scheduled to expire on Monday,
November 7, 1994.
